Abstract:

ABSTRACT Purpose: Cystic fibrosis (CF), a progressive and multi-systemic disease, causes reduced anaerobic performance. This study aimed to compare anaerobic power using two tests (Counter-movement Vertical Jump and Wingate Anaerobic Test) in CF patients and healthy children. Material and Methods: Eighteen CF and 18 healthy children were included in this prospective study. Knee extensor muscle strength and body composition were assessed with a digital handheld dynamometer and Tanita-BC 418, respectively. Anaerobic power was evaluated with Wingate Anaerobic Test (WAnT) and Counter-movement Vertical Jump (CMJ) using a triaxial accelerometer (G-Walk). Results: Maximum concentric power, peak speed, impact force, take-off force, and jump height were significantly worse in the CF group than in their healthy peers (p<0.05). CMJ parameters were found to be highly correlated with WAnT parameters, fat-free mass (FFM), body mass index (BMI), and knee extensor muscle strength (p<0.05). Conclusion: The anaerobic power is affected in mild CF patients. CMJ is an easy and effective test to evaluate anaerobic power and compare CF patients and healthy children.
